Corned Beef Tater Tot Hotdish (Casserole)

This Midwestern tater tot casserole recipe is the real deal with loads of corned beef, creamy gravy, smoked Swiss cheese, then topped with tater tots and baked golden. Perfect for leftovers!

Hotdish recipes are all the rage right now. I'm seeing them everywhere. One even popped up in my latest issue of Bon Appetit Magazine. No complaints here. They're freaking DELISH!

No apologies for liking them.

What exactly is a hotdish? And WHY is it only one word? A "hotdish" is basically a casserole. I've seen people say, "well, a hotdish uses more red meats, where a casserole typically uses lighter meats, like tuna and such..." POSH. It's a casserole, people! It's mostly a Minnesota thing, where it originated, though you'll find it all over the Midwest of America. I grew up Midwest and we just called it a casserole, but names are unimportant, as this is a recipe that you totally NEED in your life.


And no, I still don't know why "hotdish" is only one word.

A hotdish is basically a casserole made with a starch (usually potatoes), a meat, and a gravy of some sort, usually in the form of canned soup. They're easy to make and rather hearty, which is probably why people love them so much.

This version skips the canned stuff and works with only fresh ingredients. I am using the leftover corned beef I had from my Pressure Cooker Corned Beef Recipe. I LOVE having leftovers, mostly for awesome sandwiches or hash, but it totally ROCKS in this recipe. Seriously!

Let's talk about how we make our Corned Beef Tater Tot Hotdish. 

First! You'll cook down your onions, peppers, celery, potato, and garlic in a hot pan with a bit of butter. Like so...

Next, add a couple tablespoons of butter and melt it down. Stir in a couple tablespoons of flour and stir it up until it forms a roux. Cook the roux a few minutes, stirring, to brown it slightly. Pour in chicken stock and your seasonings and stir, cooking, until it thickens up and forms your gravy.


Like so...

Next, stir in the cooked corned beef and crema or sour cream. Heavy cream is more traditional, or you can use milk, but this dish is already quite thick and decadent, so I like to go just a tad lighter on it. I always prefer Mexican crema, though sour cream will work just fine.

Mmm. Creamy.

Top that baby with cheese!


I used a smoked Swiss cheese that I found at the store specifically for this recipe, as I wanted a smoky element, but a nice white cheddar would be great here.

Next, layer on your tater tots. You'll want to cover the entire top.

I'm only half way done there. OBVS.

Next, bake the whole thing at 425 degrees F for about 20 minutes or so, until the tater tots are nice and golden brown. It might take a bit longer, so keep an eye on it toward the end of the cooking time.

Check. This. Out.
